Это отлично работает на Android / Desktop:
Future<List<City>> fetchCities() async {
final response =
await http.get(globals.url + '/city',
headers: {HttpHeaders.acceptHeader: globals.apiVersion});
if (response.statusCode == 200) {
// If the call to the server was successful, parse the JSON
return compute(parseCities, response.body);
} else {
// If that call was not successful, throw an error.
print('Failed to load cities');
throw TextException(Strings.msg_session_expired);
}
}
Но при запуске как веб-приложения получаю исключение:

Есть ли способ заставить запросы http.get работать с flutter_web?
